Bug 164836 – GCC 4.3.0_alpha20070126 segfaults during configure

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Emanuel Greisen 2007-02-01 13:30:23 UTC]

When trying to install the newest GCC (gcc-4.3.0_alpha20070126) the build process dies during configuration. This is due to a test that makes the compiler do an internal error (segfault).

Reproducible: Always

Steps to Reproduce:
1. Create an ebuild that uses gcc-4.3.0_alpha20070126
2. Try to ebuild it with the use flags: "fortran gcj gtk nls (-altivec) -bootstrap -build -doc (-hardened) -ip28 -ip32r10k -mudflap (-multilib) -multislot (-n32) (-n64) -nocxx -objc -objc++ -objc-gc -test -vanilla"
3. Watch and wait, the error takes place when we are to build libgcc.

Actual Results:

Expected Results:  
Successfull compilation and installation of GCC.

I tried to run the test program that result in the segfault with the xgcc binary:
------------------------ conftest.c ------------------------
 /* confdefs.h.  */

 #define PACKAGE_NAME "GNU C Runtime Library"
 #define PACKAGE_TARNAME "libgcc"
 #define PACKAGE_VERSION "1.0"
 #define PACKAGE_STRING "GNU C Runtime Library 1.0"
 #define PACKAGE_BUGREPORT ""
 /* end confdefs.h.  */

 int
 main ()
 {

   ;
   return 0;
 }
------------------------ conftest.c ------------------------

with this command:
/var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070126/work/build/./gcc/xgcc -B/var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070126/work/build/./gcc/ -B/usr/i686-pc-linux-gnu/bin/ -B/usr/i686-pc-linux-gnu/lib/ -isystem /usr/i686-pc-linux-gnu/include -isystem /usr/i686-pc-linux-gnu/sys-include -c -O2 -march=pentium3 -pipe -O2   /tmp/conftest.c

This did result in segfault, so I guess the xgcc that is build during compilation of GCC has errors.

This is the executable that configure tries to use, it came from:

Not a bug in anything provided by Gentoo, so closing INVALID.
